Our Approach

An ethical approach to every undertaking

Surveyor on site representing professional ethics and standards.
01

Ethics

We are regulated by the Royal Institution of Chartered Surveyors and professional ethics are central to our ethos.

Surveying and inspection work that reflects efficient professional practice.
02

Efficiency

As an RICS Tech Partner we build surveying software, including in-house tools that shorten the gap between site inspection and issued report.

Office premises inspected during a dilapidations instruction, representing advice given on the evidence.
03

Integrity

Advice is given against the lease and the evidence on site, not against the outcome a client prefers. Where a defect is overstated or outside tenant liability, we say so in writing.

At our recent commercial due diligence survey of an industrial unit in East London the findings of our report led to significant financial advantages for our client. We identified several issues which equated to potential cost savings of approximately £150,000.

These findings played a pivotal role in empowering our client during lease negotiations. With the evidence provided by us, our client was able to engage confidently and effectively in discussions with the landlord. This not only facilitated a reconsideration of the lease terms but also allowed the client to negotiate a reduction in rental values and improvements to other lease-related conditions.

Our proactive approach in highlighting these issues underscores our commitment to adding tangible value to our clients' investment decisions.

By ensuring that all factors are thoroughly vetted, we position our clients in a place of strength, enabling them to make informed and advantageous decisions and negotiations.

Cost Saving
We identified issues that give rise to cost savings that equate to circa £150,000. The issues that we identified were used by the client/tenant to reconsider the lease for the property. 
In addition to this the defects that were identified allowed the client to negotiate with the landlord with regard to the rental value of the property, and other lease terms.

When Flat Roof Coverings Diverge from Standard Practice

We recently carried out a drone-based roof condition inspection in West London, where an unusual bituminous liquid-applied membrane had been installed over a zinc flat roof.

This type of overlay—reinforced with a textile mesh—is not typically encountered in applications of this kind, where polymeric systems are more commonly specified. In this case, surface discolouration, exposed reinforcement mesh, and evidence of ponding all raised concerns regarding durability and workmanship.

When flat roofing systems deviate from established detailing or product specifications, there is increased risk of premature failure—particularly when installation records or manufacturer compliance documentation are unavailable.

Early identification through external inspection can assist in defining appropriate next steps, including testing or sampling to determine whether remedial works or full replacement is required.
Roof Risk Without Internal Access

We are often instructed to assess external roof coverings where internal access is restricted. A recent case in W14 illustrates the value of high-level drone inspection for identifying latent structural concerns from the outside.

Numerous depressions in the flat roof deck suggested potential hidden deterioration of the substrate, likely linked to historical water ingress. In the absence of internal inspection, we recommended core sampling to confirm the extent of any concealed damage and to inform the appropriate scope of remedial work.

External-only inspections, when carried out systematically, can yield sufficient evidence to justify further investigation, particularly where the risk of ongoing deterioration to concealed timber or insulation is suspected.

Where Roof Design Meets Condensation Risk

Two timber-framed roof lanterns formed part of a recent external inspection we undertook on a mansard roof in West London. Both featured single glazed elements, limited overhangs, and decorative paint finishes in poor condition.

The presence of condensation to internal glazing, along with signs of historical repair and timber exposure, highlights a common set of issues—particularly in traditional or poorly detailed roof structures.

Where single glazed rooflights are retained in occupied spaces, internal dampness is frequently the result of thermal bridging or trapped moisture, rather than rainwater penetration alone.

In such cases, replacement offers the opportunity to introduce modern, thermally efficient materials and more robust junction detailing—reducing risk and improving long-term performance.

At our recent commercial due diligence survey of an industrial unit in East London, we utilised drone technology to conduct a detailed inspection of areas otherwise impossible to access, such as the roof, cladding, and high-level windows. Our surveyors, who are also fully qualified drone pilots, are registered with the Civil Aviation Authority. This ensures compliance with the highest standards of safety, particularly in urban environments where airspace restrictions are prevalent.

The drone survey captured high-resolution images and data of the relevant areas, allowing us to identify key issues that might otherwise have been missed. Specifically, we discovered significant defects in the roof and cladding, along with issues in the rainwater goods. Such findings are crucial as they hold the potential to save our client significant expenditure, mitigating risks that could escalate into costly repairs if left unaddressed.

Our ability to integrate drone technology into traditional surveying practices not only elevates the thoroughness of our inspections but also adds substantial value to our clients by providing more comprehensive insights. This case in East London is a prime example of how leveraging innovative technology can lead to advantageous outcomes for our clients, ensuring their investments are sound, and their properties are maintained to the highest standard.

DRONE SURVEY
A drone survey was undertaken which enabled a detailed inspection of the roof, cladding, and high level windows. All of our surveyors are fully qualified drone pilots and registered with the Civil Aviation Authority to fly camera drones subject to local airspace restrictions. For this survey were were able to determine significant roof defects, cladding defects, and problems with the rainwater goods that had the potential to save the client tens of thousands of pounds.

About Chiswick Park

Chiswick Park Office Buildings

Chiswick Park is a 33-acre business park on the boundary of the London Borough of Hounslow and the London Borough of Ealing, between Chiswick High Road and Gunnersbury station, developed progressively from 2000 to a masterplan by Rogers Stirk Harbour and Partners around a central landscaped lake. The park accommodates twelve six-storey HQ-grade office buildings together with an amenity building, ancillary retail and leisure floorspace, and structured car parking, operated under the Enjoy-Work management programme. Tenants include corporate occupiers across technology, media, pharmaceuticals, financial services, energy, and consumer goods. Typical building types comprise six-storey steel-framed office buildings of approximately 150,000 square feet, with floor-to-ceiling structural-glazed curtain-wall facades, exposed perimeter steel columns and roof beams, triple-height entrance atria, raised access floors, suspended ceilings, four-pipe fan-coil or underfloor air-conditioning, and parapeted single-ply flat roofs with substantial rooftop plant. Surveying instructions at Chiswick Park commonly include dilapidations and schedules of condition on office leases, category-A and category-B fit-out advice, reinstatement cost assessments, Minimum Energy Efficiency Standards strategy, and condition appraisals on curtain wall, atrium glazing, and rooftop plant.

Office Building Stock and Common Defects

The office buildings at Chiswick Park are steel-framed structures of consistent six-storey height, with floor-to-ceiling structural-glazed curtain-wall facades, exposed perimeter steel columns and roof beams, central or end-bay triple-height atria, raised access floors of 150 mm to 300 mm void depth, four-pipe fan-coil or underfloor air-conditioning, suspended ceilings, and parapeted single-ply flat roofs with extensive rooftop plant for cooling, ventilation, and emergency power. Common defects include sealant failure and gasket degradation at curtain-wall joints, water ingress at atrium glazing and rooflight perimeters, coating wear and condensation-related corrosion on exposed external steelwork, end-of-life chiller and boiler installations on the earlier buildings, raised access floor damage and inadequate void coordination after multiple fit-outs, suspended ceiling tile degradation, dated category-A finishes that fall short of current Grade A specification expectations, and flat-roof membrane ageing at upstands and outlets.

Office Dilapidations, Category-A and Category-B Fit-Out, and MEES

Tenants and landlords at Chiswick Park face material dilapidations exposure on office leases, driven by the age of building services on the earlier buildings, the cumulative impact of successive fit-outs, and the cost of returning premises to a defined category-A specification. A schedule of condition recorded at lease commencement is intended to limit terminal dilapidations liability and is routinely instructed for all new leases at the park. Terminal schedules require assessment of category-A reinstatement (raised floors, ceilings, mechanical and electrical services, perimeter finishes), removal of category-B fit-out (partitioning, joinery, IT cabling, kitchenettes, audio-visual installations), and statutory obligations including Minimum Energy Efficiency Standards. MEES strategy is increasingly central to dilapidations and asset management because letting and continued occupation under the EPC regime require careful planning around plant upgrade, lighting, and fabric improvements on the highly glazed envelope.

Reinstatement Cost Assessment and Building Refurbishment

Reinstatement cost assessments at Chiswick Park need to reflect the replacement cost of large-floorplate steel-framed office buildings with structural-glazed curtain-wall envelopes, exposed external steelwork, triple-height atria, raised access floors, fan-coil or underfloor air-conditioning services, and rooftop plant, together with professional fees, demolition and debris removal, and reinstatement of the surrounding landscape and water features. Refurbishment of the earlier 2000s buildings to current Grade A office specification, including plant replacement, lighting upgrades, end-of-trip facilities, and façade improvements, generates schedule of condition work for adjoining occupiers, party wall awards, and pre-construction condition records on neighbouring buildings. Owners considering capital expenditure on refurbishment or repositioning need early advice on existing-building condition, MEES compliance pathways, and the costs and risks of retained versus replaced building services.
